TECHNICAL FIELD

[0001] The present application relates to the technical field of optical cable pay-off rack, in particular to an adjustable optical cable pay-off rack. BACKGROUND

[0002] Optical cable pay-off rack is needed in optical cable laying operation. The mainstream optical cable pay-off rack in the industry is based on standardized design, mainly developed for regular optical cable coils with fixed size drums, and achieves support positioning through precise matching with the inner circle of the drum. It is mature in application in batch regular optical cable construction.

[0003] Patent No. CN 116986409 A discloses a pay-off rack and a pay-off rack use method, which includes a rack body and a plug-in disc mechanism. The rack body includes a bottom plate, a top plate, and a stand plate connected between the bottom plate and the top plate. The bottom plate is configured to enable the reel to roll onto the bottom plate. The plug-in disc mechanism includes a lifting frame, a lifting drive assembly, and a plug-in disc assembly. When paying off a heavy reel, the reel only needs to be pushed onto the bottom plate. The worker can adjust the height of the lifting frame through the lifting drive assembly, so that the plug-in disc assembly on the lifting frame can be aligned and inserted into the hole of the reel. Then, the lifting frame is lifted upward by the lifting drive assembly to lift the reel, so as to facilitate the rotation of the reel for paying off work.

[0004] However, the above technical solution still has the following deficiencies in actual application: In actual construction scenarios, in addition to regular optical cables, there are also a large number of scattered optical cable coils formed due to cutting, excess material recycling, etc. Such optical cable coils have no fixed inner circle structure, and the diameter size is randomly variable. At the same time, the drum sizes of different specifications of regular optical cables also differ.

The inner cavity of the plug rod clamping groove 303 is C-shaped, and the plug rod clamping groove 303 is used for clamping the upper end of the plug rod arm 301. The plug rod assembly 3 is used for blocking the rotation of the active side rotating disc 2016. When adjusting, the plug rod arm 301 is pulled down to be separated from the plug rod clamping groove 303. The lower end of the plug rod arm 301 can be inserted into the spoke outer ring 17 of the active side rotating wheel 2011 to achieve temporary limiting.

[0031] The working principle of the above embodiment is that the pay-off shaft support frame 1 is used to support the pay-off shaft part 2, the pay-off shaft part 2 is rotationally supported with the pay-off shaft support frame through flange bearings 6 at both ends, the flange bearings 6 simultaneously bear the functions of reducing friction and axial limiting, the bidirectional screw rod 2031 not only adjusts the inner side support assembly 203 but also plays the role of transmitting the power of the driving side adjusting assembly 201 and the driven side adjusting assembly 202, the working mode of the driving side rotating wheel 2011 is switched through the plug-in and pull-out of the driving side bolt 11 and the driven side bolt 13, when the bolt is inserted, the inner side support assembly 201 and the driven side adjusting assembly 202 drive the sliding block to slide to adjust the distance between the outer side rods 204, when the bolt is pulled out, the driving side rotating wheel 2011 is rotated to drive the bidirectional screw rod 2031 to rotate, the bidirectional screw rod 2031 drives the two moving sleeves to move, and then drives the support rods to support the outer side rods 204, the reinforcing rod 2036 enhances the rigidity of the pay-off shaft part 2, and at the same time, the moving sleeves are limited when the bidirectional screw rod 2031 rotates, so that the moving sleeves do not rotate with the bidirectional screw rod 2031; The take-up rotating wheel 205 drives the pay-off shaft part 2 to rotate as a whole through the connection of the rotating disc 5 to transmit the torque, the rubber pad 18 has the functions of shock absorption and buffering, and the vibration in the pay-off process is directly transmitted to the outer side rods 204, at this time, the rubber pad 18 is used to reduce the vibration transmission, when the inner side support assembly 203 is adjusted, the insertion holes of the driving side and the driven side are not aligned, the driving side rotating wheel 2011 can be continuously rotated to align the insertion holes, and then the driving side bolt 11 and the driven side bolt 13 are respectively inserted on both sides; In use, the scattered optical cable needs to be first removed from the winding drum 205, and then the scattered optical cable coil is inserted from the side of the winding drum 205 of the pay-off shaft 2. When the active side plug-in 11 and the driven side plug-in 13 on both sides are installed, the plug rod assembly 3 is pulled down, the plug rod wall is inserted into the spoke outer ring 17 of the active side rotating wheel 2011, and then the rotating side rotating disc is rotated. The active side rotating disc 2016 drives the bidirectional screw rod 2031 to rotate, the bidirectional screw rod 2031 drives the active side No. 1 adjusting disc 2014 to rotate through the active side No. 1 adjusting disc 2014, and the active side No. 2 adjusting disc 2015 is driven to rotate through the active side connecting rod 2012. The active side No. 2 adjusting disc 2015 drives the active side sliding block 2013 to slide along the No. 1 sliding groove 8 through the active side connecting rod 2012, and the bidirectional screw rod 2031 drives the driven side No. 1 adjusting disc 2023 to rotate. The driven side No. 1 adjusting disc 2023 drives the driven side No. 2 adjusting disc 2024 to rotate through the driven side plug-in 13, and the driven side No. 2 adjusting disc 2024 drives the driven side sliding block 2022 to slide along the No. 2 sliding groove 9 through the driven side connecting rod 2021. In turn, the outer side rod 204 slides outward, and the plurality of outer side rods 204 are attached to the inner side of the scattered optical cable coil to support the scattered optical cable. Then, the active side plug-in 11 and the driven side plug-in 13 on both sides are pulled out, the active side rotating wheel 2011 is continuously rotated, the active side rotating wheel 2011 drives the bidirectional screw rod 2031 to rotate, and the bidirectional screw rod 2031 drives the No. 1 moving sleeve 2034 and the No. 2 moving sleeve 2035 to move through the reinforcing rod 2036. In turn, the support plate 2032 is pushed to support the outer side rod 204. After rotating to the position, the active side plug-in 11 and the driven side plug-in 13 are inserted again. At this time, the position of the outer side rod 204 is fixed without rotating the bidirectional screw rod 2031, so as to position the position of the outer side rod 204. That is, the active side adjusting assembly and the driven side adjusting assembly jointly act to quickly adjust the distance between the outer side rods, so that the outer side rods can quickly support the scattered optical cable. After supporting, the support connecting rod pushes the support plate to be close to and tightly attached to the outer side rod to stably support and position the outer side rod, so as to avoid the outer side rod from being deviated due to the pressure of the optical cable during the pay-off process. The scattered optical cable maintains a regular shape during the pay-off process, thereby improving the pay-off preparation efficiency of the scattered optical cable.

[0032] When temporarily winding, the outer side rod 204 is first adjusted to a suitable distance, then one end of the cable is inserted between the two outer side rods 204 of the same group, then the active side plug-in 11 and the driven side plug-in 13 on both sides are pulled out, the active side rotating wheel 2011 is rotated, the support plate 2032 is attached to the outer side rod 204, and then the active side plug-in 11 and the driven side plug-in 13 are inserted after being attached. The active side rotating wheel 2011 is reversely rotated, the bidirectional screw rod 2031 drives the outer side rod 204 to be attached to the support rod through the active side adjusting assembly 201 and the driven side adjusting assembly 202, the outer side rod 204 extrudes the end of the cable to be inserted into the rubber pad 18, thereby fixing the end of the cable, and then the winding rotating disc is rotated for winding. That is, through the outer rods, the inner support assembly and the take-up rotating wheel, when taking up the cable, one end of the cable is threaded between a pair of outer rods, the support plates in the inner support assembly are attached to the outer rods under the pushing of the support connecting rods, and the outer rods clamp and fix the cable at the same time, then the take-up rotating wheel is rotated, the take-up rotating wheel drives the driven side turntable to rotate through the connecting turntable, and then drives the entire pay-off shaft part to rotate synchronously, so that the cable is wound on the outer rods to complete the taking-up operation, and no additional taking-up equipment is needed when temporary taking-up operation is needed.

[0033] When the drum cable is adapted, the take-up turntable is first disassembled, then the drum is sleeved outside the pay-off shaft part 2, then the outer rods 204 are adjusted to attach to the inner wall of the drum, and then the outer rods 204 are extruded by the support assembly to extrude the inner wall of the drum, and the active side bolt 11 and the driven side bolt 13 on both sides are inserted; That is, through the active side and driven side adjusting assembly cooperating with the bidirectional screw rod, the distance between the outer rods can be flexibly adjusted according to the inner diameter of the drum, so that the outer rods adapt to the inner side of the drum of different sizes, and the outer rods can extrude the inner wall of the drum under the action of the adjusting assembly, the friction generated by extrusion is used to enhance the connection between the drum and the pay-off shaft part, and at the same time, the inner support assembly supports the outer rods through the support plates, so as to ensure that the rotating shaft of the pay-off shaft part coincides with the rotating shaft of the drum, and in the process of paying off, the paying off is not interrupted and the resistance is not increased due to the non-coincidence of the two.
